Senior Firmware Engineer

Company Description

We are a startup product development firm that specializes in creating wearables, consumer electronics, and medical devices. Clients often approach us with unique challenges that require a creative outlook and an adaptable skill set. Some products we have contributed to include Whoop 4, Whoop MG, Nuro self-driving car, and the Lumia earpiece. 

We are looking for a Senior Firmware Engineer with 7 to 10 years of experience. This is a client-facing role where the engineer will have the opportunity to collaborate with world-class engineers while developing novel products that may not exist in the world.

Salary range for this role is ₹24,00,000 - ₹28,00,000 per annum. Within the salary range, individual pay is based on factors such as job-related skills, experience, performance, and relevant education or training. 

Job Description

• Write robust embedded firmware and connect it with user-facing software in Python, C# or similar packages to enhance early version hardware.
• Lead hardware bring-up, peripheral drivers development, and power and performance management/optimization efforts
• Debug complex, system-level, multi-component issues that span multiple layers from kernel to application
• Analyze, design, develop, and debug firmware for a wide variety of devices, including novel sensing and imaging systems, haptic devices, and audio prototypes
• Understand and implement power-management, boot loaders, scheduling, inter-processor communication, and firmware/system interfaces on RTOS and/or bare-metal environments
• Maintain thorough documentation of design changes, test results, and validation processes.
• Up to 15% travel domestically and internationally to partners, suppliers, and contract manufacturers

Examples of key technologies for our current projects include:

1. Embedded Linux, RTOS and bare metal applications on custom design platforms
2. Ultra-low power electronics and firmware including a broad range of communication technologies (Cellular, WiFi, BLE, Zigbee, NFC)
3. Microcontrollers and microprocessor systems using a range of peripherals (RTC, SPI, I2C, UART, Crypto Engines, DMA, ADCs, USB, AI/ML accelerators)

What We Are Looking For

• B.Tech (M.Tech is a plus) in electrical engineering and 7 to 10 years of full-time work experience developing complex, technical, and integrated products.
• Experience with low-level driver development, hardware abstraction layers, and working with ARM Cortex-M microcontrollers.
• Knowledge of real-time operating systems (RTOS), preferably Zephyr or FreeRTOS, and experience with version control systems (Git) and CI/CD practices.
• Proficiency with firmware development tools (CCS, MPLAB, or similar), software development tools (Python, or similar) and electrical hardware design tools (Altium or KiCAD).
• Hands-on experience debugging and validating hardware using JTAG, GTB, logic analyzers, and oscilloscopes.
• Strong background in wireless communication protocols like BLE, WiFi, NFC.
• Experience integrating and optimizing sensors and peripherals like IMUs, haptics, touch, cameras, temperature/humidity, and heart-rate monitors.
• Excellent written and verbal communication skills and comfort explaining complex engineering concepts to both technical and non-technical audiences.
• Strong problem solving and analytical skills, a willingness to get your hands dirty and a big appetite for self-directed learning.
• Familiarity with OTA updates, bootloader design, and secure firmware deployment.
• Experience with hardware‑software integration, HIL testing, bringing up new hardware platforms.

Desired but not required:

• Experience in developing high-reliability consumer products at high volumes, preferably with integrated biomedical sensors like ECG, PPG, SpO2, GSR, BIA, or similar.
• Experience with test automation frameworks and proficiency with Python, MATLAB, LabView or similar.
• Background in hardware testing and debugging, including software interfaces.
• Familiarity with regulatory testing processes for medical or consumer devices.

We know the skill-gap and "need to tick every box" can get in the way of meeting brilliant candidates, so please don't hesitate to apply – we'd love to hear from you if you meet multiple but not all the criteria listed above.

Perks and Benefits

1. Flexible Working Hours. We are guided by our client work and needs; however, you have autonomy to manage your time and diary to suit your work-life balance.
2. Total 25 days Paid Time Off (15 days privilege leave, 10 days sick leave)
3. Day off on your birthday, wedding anniversary, and child's birthday.
4. Competitive pay and an awesome bonus structure.
5. Yearly salary adjustments that keep you ahead of inflation.
